Lazarus The 2nd
Thank you very much for your response and your links.
I have tried to install and run MediaPortal, but it is too complicated (for me!). I think I need a degree in electronics or something ( or perhaps a new brain!).
The GBPVR I have tried to install before, but that did not seem to like my PC!
So, I have uninstalled both, and whilst waiting for a further reply from Sony, I will continue to search for an alternative.
I DO thank you very much again for your help and advice.
